(2) Anatomy - Skull - Facial Bones

How many Facial bones are there? List them

14

Vomer (1)

Palatine bone (2)

Inferior nasal concha (2)

Nasal bone (2)

Mandible (1)

Maxilla (2)

Lacrimal bone (2)

Zygomatic bone (2)

Vomer (1)

bne in the middle of your nose when you look up your nose

Palatine bones (2)

NOT THE Palatine Process of the Maxilla (don’t get that confused)

Inferior Nasal Concha (2)

Middle Nasal Concha (2)--not in packet but mentioned in video

Nasal Bone (2)

bridge of nose

Mandible (1)

its ya jaw babes, just a fancier word

Mandible - Coronoid process

a projection of the mandible to which muscle moving the mandible upward attaches

* the space where her right finger is pointing

Mandible - Mandibular condyle/**Condylar process**

rounded structure on the mandible that fits into the mandibular fossa on the temporal bone to form a synovial joint that allows the mandible to move. The mandibular fossa of the temporal bone and the condyle of the mandible come together to form a joint called the temporomandibular joint.

\
Condylar process contains the Mandibular condyle

(pic is the Condylar process)

Mandible - Mandibular condyle

the rounded part of the Condyla process - fits into mandibular fossa

Mandible - Alveolar process (the maxilla bone also got this on the top)

ridges on the mandible and maxilla that help to form the sockets that hold the teeth, help with attachment of teeth

Mandible - Mental foramen

the 2 holes

Mandible - Mandibular foramen

Mandible - Mental protuberance (not in handout but in video)

the chin itself

Maxilla (2)

How many landmarks does the Maxilla bone have? List them

3

Infraorbital foramen (2)

Alveolar process

Palatine process (2)

Maxilla bone - Infraorbital foramen

2 holes

Maxilla bone - Alveolar process (the Mandible bone also has this below)

holds teeth in place (upper teeth in this case)

Maxilla - Palatine Process (2)

upper roof of your mouth

Lacrimal bone (2)

How many landmarks does the Lacrimal bone have? List them

1

Nasolacrimal canal

Lacrimal bone - Nasolacrimal canal

the hole; helps drain tears into the nasal cavity

Zygomatic bone (2)

How many landmarks does the Zygomatic bone have? List them

2

Temporal process of the zygomatic bone

Zygomatic arch

Zygomatic bone - Temporal process of the zygomatic bone

(past the #4)-NOT the zygomatic process of the temporal bone

Zygomatic bone - Zygomatic arch

the zygomatic process of the temporal bone + the temporal process of the zygomatic bone form the **zygomatic arch**

\
functions as an attachment site for a muscle moving the mandible and for ligaments holding the mandible in place

**BONUS** Hyoid bone

This bone is NOT part of the skull and lies just inferior to the mandible in the anterior neck. This hyoid bone is the only bone that is not directly attached to another bone.

\
It functions as an anchor throat, larynx, and tongue muscles.

\
Fractured if strangled to death

Hyoid bone - Lesser horn

the point (what her left index finger is touching)

Hyoid bone - Greater horn

the long part
